1998 by Dr. Zhangwensong, this project is one of the earliest free software projects in China. LVS is mainly used for multi-server load balancing for the network layer. In a server cluster system built by LVS, the load balancing layer of the front end is called the director server, and the server group layer that serves the backend is called real server. Get an overview of the LVS infrastructure.LVS has three modes of operation, namely Dr (direct Routing), TUN (tunneling IP Tunneling), NAT (net

because all request packages and reply packets require the Director Server to parse and regenerate, affecting efficiency. At the same time, LVS load balancer has 10 scheduling algorithms, namely RR, WRR, LC, WLC, LBLC, LBLCR, dh, sh, sed, NQFor detailed LVS instructions, see PortalIn this paper, we will use LVS to realize MySQL read-write load balancing, keepalived Avoid single point of failure of nodes.Lvs+keepalived Configuring the Environment prep

Summer came again, outside hot as the oven, as a fear of heat more afraid of the young girls, I do not want to go out shooting meaning. Some time ago found that the school staircase has a light blue wall, a little natural daylight, very praise, probably this summer will have a fixed shooting place. This group of photo tones is a faint blue, very pleasing, just need to simply adjust a tune can be. So I'm here to share with you how I'm going to pull out this color. Of course, the previous shooti

best choice. The hardware that determines whether the PC can output 4K resolution is the video card, currently only Kepler architecture, GCN architecture, or the stand-alone graphics that update the architecture support output 4K resolution, the set platform aspect will use Haswell architecture processor or Kaveri APU side can support. First, let's look at how the set up platform outputs the 4K resolution, and the Intel platform must be equipped with the HD Graphics 4200/

technology is very general, performance promotion is very limited, and desktop dual-card fire is not comparable. Since only changed the name of the exchange of fire, and the principle of the exchange of fire does not really change, so for the new Kaveri Apu Crossfire, I still do not optimistic. The i7-4500u is mounted with a kernel of HD 4400 and is not Intel's strongest iris and iris Pro Display Mystery 2: Overall positioning improve,

According to colleagues at the scene, the server suddenly slowed down and stopped the network service until all the responses were stopped. In order to restore the service, they only have to restart the server. After forcing the server to reboot, a blue screen appears, the System reports stop:0x0000
